My scenario is Idoc to jdbc..
I m able to successfully send the idoc from R3 and it is received in XI also.
However the message does not reach to database and am getting the following error in RWB of XI.
"Error when attempting to get processing resources: com.sap.aii.af.service.util.concurrent.ResourcePoolException: Unable to create new pooled resource: DriverManagerException: Cannot establish connection to URL 'jdbc:oracle:thin:@172.25.XX.XXX:1521:<SID>': SAPClassNotFoundException: oracle.jdbc.driver.OracleDriver"
Kindly tell me where the problem is.
